摘要: Vahiuuringute uheks keskseks eesmargiks on vahirakke normaalsetest rakkudest eristavate ravimite valjatootamine. Kliinilises kasutuses olevate vahiravimite puuduseks nende vahene selektiivsus ja sellest tingitud korvalmojud normaalsetes kudedes. Artiklis antud ulevaade suunatud valjatootamisest suundumustest. Suunatud vahiravi pohineb molekulaarsetel erinevustel vahikoe normaalsete veresoonte vahel. In vivo faagidisplei meetodi abil voimalik haigusspetsiifilisi molekulaarseid mustreid kaardistada. Selle tulemuseks peptiidid, mis seostuvad selektiivselt vahiveresoontega. Need kullerpeptiidid nagu ka teised kasvaja veresoontega seonduvad molekulid (antikehad, aptameerid) voimaldavad kasvajasse viia vahiravimeid kontrastaineid. Hiljuti avastatud kasvajakude penetreerivad peptiidid pohjustavad vahiveresoonte selektiivset lekkimist. Koos ravimitega manustatuna need ravimi valjumist veresoontest tungimist kasvajakoesse – terapeutilise indeksi paranemine.Eesti Arst 2015; 94(5):281–287
